Swap Floppy Drive; Boot Up Floppy Seek; Boot Up Numlock Status; Gate A20 Option - Aaeon SBC-659P User Manual

Swap Floppy Drive

This field is effective only in systems with two floppy drives.
Selecting enabled assigns physical drive B to logical drive A, and
physical drive A to logical drive B.

Boot Up Floppy Seek

When Enabled, the BIOS tests (seeks) floppy drives to determine
whether they have 40 or 80 tracks. Only 360-KB floppy drives
have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB
capacity all have 80 tracks. Because very few modern PCs have
40-track floppy drives, we recommend that you set this field to
Disabled to save time.

Boot Up NumLock Status

Toggle between On or Off to control the state of the NumLock key
when the system boots. When toggled On, the numeric keypad
generates numbers instead of controlling cursor operations.
Boot Up System Speed
Select High to boot at the default CPU speed; select Low to boot at
the speed of the AT bus. Some add-in peripherals or old software
(such as old games) may require a slow CPU speed. The default
setting is High.

Gate A20 Option

Gate A20 refers to the way the system addresses memory above 1
MB (extended memory). When set to Fast, the system chipset
controls Gate A20. When set to Normal, a pin in the keyboard
controller controls Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.
